Had an outage on my home cable network which may have been related to weekend reports of midwest AT&T issues (I use Qwest). The outage started Saturday evening and lasted until Sunday morning. The cable modem lost connection and reverted to its default internal IP (192.168.100.14).
A note to myself not to mess with the Internet On/Off button on the device. Since it didn’t behave like a switch (when you push it, it doesn’t sink in and stay in and then pop out with a second push), I didn’t think it would save state over a power cycle. Alas, 2 hours after physical connectivity returned, I finally hit the button and everything came back up.
On the bright side, my IP was not renewed. Pretty odd for that long of an outage.
